DETAILED DESCRIPTION

FIG. 1 illustrates a system block diagram of an air conditioning systemaccording to an embodiment of the instant disclosure. As shown in FIG.1, the air conditioning system 1 of the embodiment comprises a main pipe10, multiple area pipes (e.g., there are two area pipes in theembodiment, respectively called first area pipe 20 and second area pipe30), and a controller 40. In some embodiments, the air conditioningsystem 1 can be a cold air conditioning system or a warm airconditioning system for adjusting indoor temperature inside buildings(e.g., office buildings, residential buildings, department stores, orhypermarkets).

FIG. 2 illustrates a system block diagram of an air conditioning systemaccording to an embodiment of the instant disclosure. As shown in FIG. 1and FIG. 2, the air conditioning system 1 of the embodiment is a coldair conditioning system and can be applied for a multi-story building.The main pipe 10 of the air conditioning system 1 comprises a storagetank 11, a water supply pipe 12, and a water return pipe 13 connectedwith one another in series to form a loop. The storage tank 11 can be achilled water tank 111 of a water chiller unit 2. In some embodiments,the water chiller unit 2 may comprise a compressor, e.g., a centrifugalcompressor, a scroll compressor, a screw compressor, or a reciprocatingcompressor. The water chiller unit 2 can make water which returns fromthe water return pipe 13 cooled down to form a water fluid F (coldwater) with predetermined operating temperature (5° C., 7° C., or 8° C.)stored in the storage tank 11.

In addition, the water supply pipe 12 and the water return pipe 13 ofthe main pipe 10 may extend to each of the floors. The main pipe 10 isfurther connected with a variable-frequency pump 14 in series todynamically drive the water fluid F to cyclically flow in the main pipe10. For example, the variable-frequency pump 14 can operate underdifferent operating frequencies (e.g., the variable-frequency pump 14can operate under operating frequencies between 30 Hz and 60 Hz) anddynamically controls and drives flow rate of the water fluid F in themain pipe 10. For example, the flow rate of the main pipe 10 while thevariable-frequency pump 14 operates under 60 Hz is greater than that ofthe main pipe 10 while the variable-frequency pump 14 operates under 30Hz.

As shown in FIG. 1 and FIG. 2, multiple area pipes of the airconditioning system 1 are disposed on different floors with differentheights. In the embodiment, the storage tank 11 is disposed at abasement. The first area pipe 20 is disposed on first floor, and thesecond area pipe 30 is disposed on second floor. The first area pipe 20is connected with the main pipe 10 in parallel and comprises a firstwater supply branch pipe 21, at least one heat-exchange box 22 (e.g.,there are two heat-exchange boxes 22 in the embodiment), and a firstwater return branch pipe 23 connected with one another in series to forma loop. In an embodiment, the heat-exchange box 22 can be a chilled airbellow 221, the first water supply branch pipe 21 is connected with thewater supply pipe 12 of the main pipe 10, the first water return branchpipe 23 is connected with the water return pipe 13 of the main pipe 10,and the two heat-exchange boxes 22 can be connected between the firstwater supply branch pipe 21 and the first water return branch pipe 23 inseries or in parallel. Thereby the water fluid F (cold water) in thestorage tank 11 can flow to the two heat-exchange boxes 22 through thewater supply pipe 12 and the first water supply branch pipe 21 and forma water fluid F1 with higher temperature (e.g., 11° C., 12° C., or 13°C.) after the water fluid F is heat exchanged in the heat-exchange box22. The water fluid F1 flows to the water chiller unit 2 through thefirst water return branch pipe 23 and the water return pipe 13 to becooled down. In some embodiments, the temperature of the water fluid F1dynamically varies according to a thermal loading amount of the firstarea pipe 20. For example, the greater the load of the heat-exchange box22 is, the higher the temperature of the water fluid F1 would be;alternatively, the more the heat-exchange boxes 22 are used, the higherthe temperature of the water fluid F1 would be.

In an embodiment, the first area pipe 20 is further connected with afirst electric valve 24 and a first calorimeter 25 in series. As shownin FIG. 2, the first electric valve 24 of the embodiment is connectedbetween the water supply pipe 12 and the first water supply branch pipe21 to control a flow rate of the water fluid F which flows through thefirst area pipe 20. For example, the greater the amplitude of an openingof the first electric valve 24 is, the greater the flow rate of thefluid flowing through the first area pipe 20 would be. The firstcalorimeter 25 can detect and transmit a first dynamic thermalinformation D1. The first dynamic thermal information D1 is atemperature information, a heat-exchange amount, or a combination of thetemperature information and the heat-exchange amount of the water fluidin the first area pipe 20. For example, the first calorimeter 25 can bea thermometer for detecting the temperature information of the waterfluid in the first area pipe 20 (e.g., the temperature of the waterfluid F of the first water supply branch pipe 21 and the temperature ofthe water fluid F1 of the first water return branch pipe 23);alternatively, the first calorimeter 25 can be a thermal detector (e.g.,a BTU meter) for detecting the heat-exchange amount of the water fluidin the first area pipe 20.

In an embodiment, the first calorimeter 25 may comprise at least onethermometer, a flowmeter, or a combination of the thermometer and theflowmeter. As shown in FIG. 2, the first calorimeter 25 of theembodiment comprises a water supply thermometer 251, a water returnthermometer 252, and a flowmeter 253. The water supply thermometer 251and the flowmeter 253 are disposed on the first water supply branch pipe21 for detecting the temperature (e.g., 6° C., 7° C., or 8° C.) and theflow rate (e.g., 100 LPM, 200 LPM, or 300 LPM) of the water fluid F inthe first water supply branch pipe 21. The water return thermometer 252is disposed on the first water return branch pipe 23 for detecting thetemperature (e.g., 10° C., 12° C., or 14° C.) of the water fluid F1 inthe first water return branch pipe 23. The first calorimeter 25 mayfurther comprise a microprocessor 254. The microprocessor 254 cancalculate the heat-exchange amount of the first area pipe 20 (e.g., 1BTU, 2 BTU, or 5 BTU) according to the product of the difference intemperature between the water fluid F and the water fluid F1 and theflow rate in the first water supply branch pipe 21.

As shown in FIG. 2, the second area pipe 30 is connected with the mainpipe 10 and the first area pipe 20 in parallel. The second area pipe 30comprises a second water supply branch pipe 31, at least one heatexchanger 32 (e.g., there are two heat exchangers 32 in the embodiment),and a second water return branch pipe 33 connected with one another inseries to form a loop. In an embodiment, the heat exchanger 32 may be acold are box 321. The second water supply branch pipe 31 is connectedwith the water supply pipe 12 of the main pipe 10. The second waterreturn branch pipe 33 is connected with the water return pipe 13 of themain pipe 10. The two heat exchangers 32 can be connected between thesecond water supply branch pipe 31 and the second water return branchpipe 33 in series or in parallel. Thereby the water fluid F (cold water)in the storage tank 11 can flow to the two heat exchangers 32 throughthe water supply pipe 12 and the second water supply branch pipe 31 andform a water fluid F2 with higher temperature (e.g., 11° C., 12° C., or13° C.) after the water fluid F is heat exchanged in the heat exchangers32. The water fluid F2 flows to the water chiller unit 2 through thesecond water return branch pipe 33 and the water return pipe 13 to becooled down. In some embodiments, the temperature of the water fluid F2dynamically varies according to a thermal loading amount of the secondarea pipe 30. For example, the greater the load of the heat exchanger 32is, the higher the temperature of the water fluid F2 would be;alternatively, the more the heat exchangers 32 are used, the higher thetemperature of the water fluid F2 would be.

In some embodiments, the second area pipe 30 is further connected with asecond electric valve 34 and a second calorimeter 35 in series. As shownin FIG. 2, the second electric valve 34 of the embodiment is connectedbetween the water supply pipe 12 and the second water supply branch pipe31 to control a flow rate of the water fluid F which flows through thesecond area pipe 30. For example, the greater the amplitude of anopening of the second electric valve 34 is, the greater the flow rate ofthe fluid flowing through the second area pipe 30 is. The secondcalorimeter 35 can detect and transmit a second dynamic thermalinformation D2. The second dynamic thermal information D2 is atemperature information, a heat-exchange amount, or a combination of thetemperature information and the heat-exchange amount of the water fluidin the second area pipe 30. For example, the second calorimeter 35 canbe a thermometer for detecting the temperature information of the waterfluid in the second area pipe 30 (e.g., the temperature of the waterfluid F in the second water supply branch pipe 31 and the temperature ofthe water fluid F2 in the second water return branch pipe 33);alternatively, the second calorimeter 35 can be a thermal detector(e.g., a BTU meter) for detecting the heat-exchange amount of the waterfluid in the second area pipe 30.

In an embodiment, the second calorimeter 35 may comprise at least onethermometer, a flowmeter, or a combination of the thermometer and theflowmeter. As shown in FIG. 2, the second calorimeter 35 of theembodiment comprises a water supply thermometer 351, a water returnthermometer 352, and a flowmeter 353. The water supply thermometer 351and the flowmeter 353 are disposed on the second water supply branchpipe 31 for detecting the temperature (e.g., 6° C., 7° C., or 8° C.) andthe flow rate (e.g., 100 LPM, 200 LPM, or 300 LPM) of the water fluid Fin the second water supply branch pipe 31. The water return thermometer352 is disposed on the second water return branch pipe 33 for detectingthe temperature (e.g., 10° C., 12° C., or 14° C.) of the water fluid F2in the second water return branch pipe 33. The second calorimeter 35 mayfurther comprise a microprocessor 354. The microprocessor 354 cancalculate the heat-exchange amount of the second area pipe 30 (e.g., 1BTU, 2 BTU, or 5 BTU) according to the product of the difference intemperature between the water fluid F and the water fluid F2 and theflow rate in the second water supply branch pipe 31.

The controller 40 may be a microprocessor, a microcontroller, a digitalsignal processor, a microcomputer, a central process unit, a fieldprogrammable gate array, or a logic circuit. The controller 40 iselectrically connected with the first calorimeter 25, the secondcalorimeter 35, the variable-frequency pump 14, the first electric valve24, and the second electric valve 34.

FIG. 6 illustrates a flow chart of an air conditioning control methodaccording to an embodiment of the instant disclosure. As shown in FIG.6, the controller 40 can receive the first dynamic thermal informationD1 outputted by the first calorimeter 25 and the second dynamic thermalinformation D2 outputted by the second calorimeter 35 (step S01) andcalculate a total water supply amount, a first water supply amount, anda second water supply amount according to the first dynamic thermalinformation D1 and the second dynamic thermal information D2 (step S02).Further, the controller 40 can control the operation of the firstelectric valve 24 to supply the first area pipe 20 with the first watersupply amount (step S03), control the operation of the second electricvalve 34 to supply the second area pipe 30 with the second water supplyamount (step S04), and control the operation of the variable-frequencypump 14 to supply the main pipe 10 with the total water supply amount(step S05). The following is an example. Please refer to FIG. 2 andTable 1 as below.

TABLE 1 The number of Heat- exchange box/ Floor Heat exchangerPercentage Flow rate 1F 2 40% 200 LPM 2F 3 60% 300 LPM Total 5 100% 500LPMIn a case of a two-story building, a demanded flow rate is 200 LPM whilethe two heat-exchange boxes 22 of the first area pipe 20 at first floorare turned on, and a demanded flow rate is 300 LPM while the three heatexchangers 32 of the second area pipe 30 at second floor are turned on.In the meantime, the variable-frequency pump 14 operates under anoperating frequency (e.g., 50 Hz) such that the total flow rate of thewater fluid F (cold water) outputted by the water supply pipe 12 is 500LPM to satisfy the demand of the flow rates of the first area pipe 20and the second area pipe 30.

As shown in FIG. 2, while the business hours of the first floor are overand the two heat-exchange boxes 22 are turned off, the temperature ofthe water fluid F1 (i.e., the first dynamic thermal information D1)detected by the first calorimeter 25 lowers. On the other hand, theheat-exchange amount of the water fluid (i.e., the first dynamic thermalinformation D1) in the first area pipe 20 also lowers, which means thatthe amount of the cold water of the first area pipe 20 in demand lowers.The controller 40 calculates a first water supply amount (e.g., 100 LPM)that the first area pipe 20 demands at present according to thetemperature information or the heat-exchange amount, and correspondinglycontrols the first electric valve 24 to decrease the amplitude of theopening thereof, such that the flow rate flowing to the first area pipe20 lowers from 200 LPM to 100 LPM. Meanwhile, the total flow rate in thewater return pipe 13 lowers synchronously (e.g., lowering to 400 LPM).The control 40 can further lower the operating frequency of thevariable-frequency pump 14 (e.g., lowering from 50 Hz to 40 Hz) inresponse to the variation of the first dynamic thermal information D1 soas to lower the total flow rate of the water fluid F outputted by thewater supply pipe 12 from 500 LPM to 400 LPM.

In another case, as shown in FIG. 3, the temperature of the water fluidF2 (i.e., the second dynamic thermal information D2) detected by theheat exchanger 32 would rise while the second area pipe 30 at the secondfloor is added with another one heat exchanger 32. On the other hand,the heat-exchange amount of the water fluid (i.e., the second dynamicthermal information D2) in the second area pipe 30 also rises, whichmeans that the amount of the cold water of the second area pipe 30 indemand rises. The controller 40 calculates a second water supply amount(e.g., 400 LPM) that the second area pipe 30 demands at presentaccording to the temperature information or the heat-exchange amount,and thereby the control 40 can control the second electric valve 34 toincrease the amplitude of the opening thereof, such that the flow rateflowing to the second area pipe 30 rises from 300 LPM to 400 LPM.Meanwhile, the total flow rate in the water return pipe 13 risessynchronously (e.g., rising to 600 LPM). The control 40 can furtherraise the operating frequency of the variable-frequency pump 14 (e.g.,rising from 50 Hz to 60 Hz) in response to the variation of the seconddynamic thermal information D2 so as to raise the total flow rate of thewater fluid F outputted by the water supply pipe 12 from 500 LPM to 600LPM.

Concisely, according to embodiments of the instant disclosure, theamplitudes of the openings of the first electric valve 24 and the secondelectric valve 34 and the operating frequency of the variable-frequencypump 14 can be adjusted immediately according to dynamic variations ofthe first dynamic thermal information D1 and the second dynamic thermalinformation D2, so that the consumed power of the variable-frequencypump 14 and the lift of pump can be effectively lowered. Further, flowrate in an unused area can be lowered, and consumption of bending pipes,valve components, and joint heads can be also lowered. The result ofpower saving can be reached. In addition, along with the lowering of theconsumed power of the variable-frequency pump 14, the loading amount ofthe water chiller unit 2 can also be lowered so as to reduce theconsumption rate.

In some embodiments, the controller 40 can comprise multiple controlunits (e.g., a first control unit, a second control unit, and a generalcontrol unit). The first control unit may be connected with the firstelectric valve 24 to control the amplitude of the opening of the firstelectric valve 24 according to the variation of the first dynamicthermal information D1. The second control unit may be connected withthe second electric valve 34 to control the amplitude of the opening ofthe second electric valve 34 according to the variation of the seconddynamic thermal information D2. The general control unit may beconnected with the variable-frequency pump 14 to control the operatingfrequency of the variable-frequency pump 14 according to thevariation(s) of the first dynamic thermal information D1 and/or thesecond dynamic thermal information D2.

In an embodiment, as shown in FIG. 2 and FIG. 5, the main pipe 10 canfurther comprise a general calorimeter 15. The general calorimeter 15detects and transmits a total dynamic thermal information Dt. The totaldynamic thermal information Dt is a temperature information, aheat-exchange amount, or a combination of the temperature informationand the heat-exchange amount of the water fluid in the main pipe 10. Thetotal dynamic thermal information Dt relates to the first dynamicthermal information D1 and the second dynamic thermal information D2.For example, the total dynamic thermal information Dt synchronouslyvaries along with the variation(s) of the first dynamic thermalinformation D1, the second dynamic thermal information D2, or thecombination of thereof. For example, the total dynamic thermalinformation Dt is a heat-exchange amount of the main pipe while thefirst dynamic thermal information D1 and the second dynamic thermalinformation D2 are respectively heat-exchange amounts of the first areapipe 20 and the second area pipe 30. While the first dynamic thermalinformation D1 or the second dynamic thermal information D2 lowers, thetotal dynamic thermal information Dt lowers correspondingly. Thecontroller 40 can dynamically adjust the operating frequency of thevariable-frequency pump 14 directly according to the variation of thetotal dynamic thermal information Dt. For example, while the totaldynamic thermal information Dt lowers, the controller 40 correspondinglylower the operating frequency of the variable-frequency pump 14 to reacha result of power saving.

In an embodiment, as shown in FIG. 2, the general calorimeter 15 maycomprise a general water supply thermometer 151, a general water returnthermometer 152, and a general flowmeter 153. The general water supplythermometer 151 and the general flowmeter 153 are disposed on the watersupply pipe 12 to respectively detect the temperature information andthe flow rate of the water fluid in the water supply pipe 12. Thegeneral water return thermometer 152 is disposed on the water returnpipe 13 to detect the temperature of the water fluid in the water returnpipe 13. In an embodiment, the general flowmeter 153 may furthercomprise a microprocessor 154. The microprocessor 154 can calculate theheat-exchange amount of the main pipe 10 according to the product of thedifference in temperature between the water fluid in the water supplypipe 12 and the water fluid in the water return pipe 13 and the flowrate of the water fluid in the water supply pipe 12.

In an embodiment, the first area pipe 20 and the second area pipe 30 maybe respectively disposed on different areas with different distancesfrom the variable-frequency pump 14. In a case, as shown in FIG. 4, thefirst area pipe 20, the second area pipe 30, and the variable-frequencypump 14 may be disposed on the same floor, and the first area pipe 20 iscloser to the variable-frequency pump 14 than the second area pipe 30is.

In an embodiment, as shown in FIG. 4, the air conditioning system 1 canbe a warm air conditioning system. The storage tank 11 can be a hotwater tank 112 of a water heater unit 3. The heat-exchange box 22installed on the first area pipe 20 and the heat exchanger 32 installedon the second area pipe 30 can be heated air bellows 222, 322. The waterfluid (warm water) in the storage tank 11 flows to the two heat-exchangeboxes 22 through the water supply pipe 12 and the first water supplybranch pipe 21 and forms a water fluid with lower temperature after thewater fluid is heat exchanged in the heat-exchange box 22. Further, thewater fluid flows to the water heater unit 3 through the first waterreturn branch pipe 23 and the water return pipe 13 to be heated.Analogously, the water fluid (warm water) in the storage tank 11 alsoflows to the two heat exchangers 32 through the water supply pipe 12 andthe second water supply branch pipe 31 and forms a water fluid withlower temperature after the water fluid is heat exchanged in the heatexchanger 32. Further, the water fluid flows to the water heater unit 3through the second water return branch pipe 33 and the water return pipe13 to be heated.

As shown inFIG. 7, in an embodiment, after the controller 40 receives the firstdynamic thermal information D1 outputted by the first calorimeter 25 andthe second dynamic thermal information D2 outputted by the secondcalorimeter 35 (step S01), the controller 40 calculates a total watersupply amount according to the first dynamic thermal information D1 andthe second dynamic thermal information D2 (step S021). Further, thecontroller 40 controls the operation of the variable-frequency pump 14to supply the main pipe 10 with the total water supply amount (stepS05).

As shownin FIG. 8, in an embodiment, after the controller 40 receives the firstdynamic thermal information D1 outputted by the first calorimeter 25 andthe second dynamic thermal information D2 outputted by the secondcalorimeter 35 (step S01), the controller 40 calculates the first watersupply amount and the second water supply amount merely according to thefirst dynamic thermal information D1 and the second dynamic thermalinformation D2 (step S022). Further, the controller 40 controls theoperation of the first electric valve 24 to supply the first area pipe20 with the first water supply amount (step S03) and controls theoperation of the second electric valve 34 to supply the second area pipe30 with the second water supply amount (step S04).
